I looked into the automatic margins issue a long time ago and I seem to remember it was caused by the firmware (SeaBIOS) configuring the terminal and QEMU just never returning it to the original state. I eventually gave up trying to fix it because I was having trouble finding a reliable point in QEMU shutdown sequence to enable the capability back. Nowadays I just run 'tput smam' after quitting QEMU. Not a lot of help, I know. Hopefuly someone else has more information about this. I'd be interested in finding a proper solution for this situation.
